Abstract: A transmitter is disclosed. The transmitter has an RF portion having an amplifier for amplifying a signal for transmission. The RF portion is fed by a baseband portion. The baseband portion comprises: means for generating a pair of in-phase (I) and quadrature-phase (Q) data signals; and a limiter arrangement for preventing the amplitude of both the I and Q data signals exceeding a pretermined level.

Abstract: A method and apparatus for receiving a radio frequency signal and a method and apparatus for transmitting a modulation signal in a multiple channel radio system. The method for receiving the radio frequency signal involves mixing the radio frequency signal with a demodulating signal, tunable in frequency steps greater than the channel spacing of the multiple channel radio system to facilitate rapid frequency adjustments. The resultant intermediate signal is then mixed with another demodulating signal, tunable in relatively smaller frequency steps in order to select the channel containing the radio frequency signal.
